Hemisphere GNSS has made significant achievements with its GradeMetrix OEM toolkit for high-precision GNSS-based machine control and guidance applications and systems. Hemisphere has expanded its portfolio of hardware offerings, including the A222 Scalable GNSS Smart Antenna introduced in November 2017, and made significant strides forward with its next-generation GradeMetrix OEM application software platform. Whether it is grading, mining, excavating, drilling and piling, or compaction applications, heavy equipment manufacturers can rebrand the solution and drive feature requirements to sell as their own. Hemisphere made the announcement at Intermat Paris 2018, where the company is exhibiting at stand 6 J 027. The GradeMetrix toolkit allows OEMs to select components, a-la-carte or as complete solutions, based on their accuracy and durability requirements and integrate into their machines to design their own IP. This allows manufacturers to maintain a competitive advantage in the marketplace, as they do not have to compete with conventional or traditional machine control and guidance dealers selling aftermarket systems, the company said. Hemisphere owns the design of the toolkit and its components and ensures each component is reliable with guaranteed compliance through design. The fully customizable and flexible toolkit provides the ability to tailor displays and outputs, per OEM requirements, and also offers OPA (open architecture) for implementing inputs and third-party sensors already available on machines. Through UniStrong, Hemisphere’s parent company, the GradeMetrix toolkit also has seamless access to complimentary and innovative technologies. This allows for much faster times to market, driving increased revenue streams for OEMs, and provides a high cost/value ratio. “The feedback we are receiving from OEMs already using our GradeMetrix toolkit is outstanding,” said Randy Noland, vice president of Global Sales & Business Development with Hemisphere GNSS. “For the first time in our industry, we are offering OEMs the opportunity to build their own machine control and guidance systems using their specifications and offering it to their customers, with their brand, 100% of the time.” Manufacturers are looking for flexibility and price performance in existing system offerings or in new systems. Hemisphere continues to provide anfull system OEM positioning solution toolkit for building powerful, complete or a-la-carte machine control and guidance systems including GradeMetrix OEM application software and an array of compatible GNSS hardware components. These include IronOne Rugged Display & Computer, A222 Scalable GNSS Smart Antenna, A326 Rugged GNSS Smart Antenna, Vector VR500 Rugged All-In-One Smart Antenna, Vector VR1000 Rugged GNSS Receiver, and C321+ RTK Base & Rover with SiteMetrix Site Management Software.
